Try.

I'm always mad at you.

I just want you to go away.

but that's what I always do;

when things get bad I never stay.

I'm the first one to want to leave

I can't live like this for long,

but that's what I always do;

although I know it's wrong.

Even if I treat you bad,

even if I'm acting strange

I'm trying my very hardest for you;

I'm trying hard to change.
